Right now I can think of very few white-collar jobs that I would feel comfortable training 4+ years for (let alone spending money or taking on debt to do so). It is far from a guarantee that almost any 4-year degree you enroll in today will have any value in four years. That has basically never before been true, even in tech. Blue collar jobs are clearly safer, but I wouldn't say safe. Robotics is moving fast too.
I really can't imagine the social effects of this reality being positive, absent massive and unprecedented redistribution of the wealth that the productivity of AI enables.
